I caused the Golden apocalypse and it felt good.
There's a square next to you PSN name that has a color. In order it goes from Light Blue(G)>Blue(F)>Dark Green(E)>Green(D)>Yellow( C)>Orange(B)>Pink(A).
The hotter color you are, the higher rank you are. Only colors of the same rank will affect each other, so you can only increase/decrease your color by fighting the same color. You nerfed my orange into a yellow and in exchange I allowed two Golden Tagers on screen.
